I installed 2.4.0-test13-pre4 which includes LVM 0.9, and the lvm tools
from http://distro.conectiva.com.br/experimental/.
Now, when I try to boot the new kernel, I get the following message from
vgscan:
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" can't get data of
volume group "vg1" from physical volume(s)
vgscan -d says (complete output available, but a little bit to long for
the list I think)
[...]
<1> vg_read_with_pv_and_lv -- BEFORE for LV
<1> vg_read_with_pv_and_lv -- vg_this->lv[0]->lv_allocated_le: 169
<1> vg_read_with_pv_and_lv -- LEAVING with ret: -365
<1> lvm_error -- CALLED with: -365
[...]
I added another debug output which tells me the counted number of
pe's (the variable npe). It is 75.
This is strange because lv no. 0 is on one disk. But it's not continous,
and after le no. 75, there is a jump backwards to a lower pe number:
--- Logical extents ---
LE PV PE reads writes
00000 /dev/hda5 00190 11 2
[...]
00073 /dev/hda5 00263 0 0
00074 /dev/hda5 00264 0 0
00075 /dev/hda5 00265 0 0
00076 /dev/hda5 00139 0 0
00077 /dev/hda5 00140 0 0
But I don't see how this could cause a problem.
A difference between the output of 0.8's vgscan -d and 0.9's vgscan -d
is that the order of pv is different:
<333> vg_read -- pv[0]->pv_name: "/dev/hda5"
<333> vg_read -- pv[1]->pv_name: "/dev/sda2"
<333> vg_read -- pv[2]->pv_name: "/dev/hdc4"
vs.
<333> vg_read -- pv[0]->pv_name: "/dev/sda2"
<333> vg_read -- pv[1]->pv_name: "/dev/hda5"
<333> vg_read -- pv[2]->pv_name: "/dev/hdc4"
